Abstract

The utility model relates to an apparatus for recovering and utilizing charring flue dust, comprising a charring kiln, a flue dust collection pipeline, a cooling separating tank, an air-guiding machine and a drying stove. The charring kiln, the cooling separating tank, the air-guiding machine and the drying stove are orderly connected through the flue dust collection pipeline. This apparatus can collect and burn fuel dust generated by mechanism charcoal charring kiln and can be used for preheating and drying sawdust; it not only saves energy resource, but absolutely eliminates environmental pollution caused by flue dust generated by mechanism charcoal charring process.

Description

The recovery of charing flue dust and use device

Technical field

The utility model relates to a kind of environmental protection retracting device, especially a kind of flue dust recycle device.

Background technology

Flue dust is as a kind of harmful substance that produces in people life and the production process, not only serious harm our environment of depending on for existence, but also caused the significant wastage of resource.Charcoal has purposes very widely in people's daily life, but in the charcoal production process, the volume of smoke of generation is seriously polluting the mode of production of our environment, particularly some small workshop modes, by all round resident is abhored.Along with the raising of people's environmental consciousness, banning or improve the mode of production has become the problem that people make great efforts to solve.At present, though some cities are devoted to replace workshop-based production with large-scale production, perhaps these factories are moved out of densely populated living area, if fundamentally do not eliminate these flue dust, it is contaminated environment still; In addition, contain the great number of flammable material in these flue dust, simple discharging also is the waste to the energy.

Summary of the invention

The purpose of this utility model is to provide a kind of recovery and use device of charing flue dust, by flue dust is compiled recovery, and with its burning, reaches the purpose of eliminating environmental pollution, energy savings.

The technical scheme that its technical problem that solves the utility model adopts is: the recovery and the use device that design a kind of charing flue dust, be made up of carbonizing kiln, smoke collection pipe road, refrigerated separation jar, air-introduced machine and drying oven, wherein carbonizing kiln, refrigerated separation jar, air-introduced machine and drying oven are connected by the smoke collection pipe road successively.In the recovery and use device of this charing flue dust, be connected in series by the smoke collection pipe road, even 100 carbonizing kilns are connected in series by the smoke collection pipe road by one, carbonizing kiln more than two or two.On the smoke collection pipe road in every carbonizing kiln flue dust exit, the flue dust control valve is housed, need to select the carbonizing kiln flue dust of utilization; On the smoke collection pipe road between air-introduced machine and the drying oven, flow control valve is housed, with the flow of control flue dust.Mainly contain carbon monoxide, methane, wood tar and carbon granules in the flue dust that retort produces, these flue dust are by the effect of air-introduced machine, compile in the smoke collection pipe road, at first cool off in jar by the refrigerated separation jar, isolate liquid such as wood tar, remaining flue dust continues to be transported to by the smoke collection pipe road combustion chamber of sawdust drying oven, burn, be used for the preheating and the oven dry of sawdust, the gas after the burning mainly contains carbon dioxide and steam, is discharged by chimney.

The recovery and the use device of the charing flue dust that the utility model provides, the flue dust that the charcoal carbonizing kiln produces can be compiled burning, be used for the preheating and the oven dry of sawdust, not only saved the energy, and the gas after the burning reaches discharging standards fully, thoroughly eliminated the pollution to environment of the flue dust that produced in the charcoal carbonization process.To produce 3 tons of charcoals daily is example, ten thousand yuan of annual expense 12-15 capable of saving fuel.This plant investment is few, technology is simple, and is easy to operate, has good social benefit and high economic benefit.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

Fig. 1 is the recovery of charing flue dust and the structure flow chart of use device.

Among Fig. 1,1. carbonizing kiln, 2. smoke collection pipe road, 3. refrigerated separation jar, 4. air-introduced machine, 5. drying oven, 6. flue dust control valve, 7. flow control valve.

The specific embodiment

The recovery and the use device of the charing flue dust that embodiment 1. is made up of three carbonizing kilns 1, smoke collection pipe road 2, refrigerated separation jar 3, air-introduced machine 4 and drying oven 5, wherein carbonizing kiln 1, refrigerated separation jar 3, air-introduced machine 4 and drying oven 5 are connected by smoke collection pipe road 2 successively, and on the smoke collection pipe road 2 in every carbonizing kiln 1 flue dust exit flue dust control valve 6 is housed, with the flow of control flue dust; On the smoke collection pipe road 2 between air-introduced machine 4 and the drying oven 5, flow control valve 7 is housed, with the flow of control flue dust.The flue dust that retort 1 produces is by the effect of air-introduced machine 4, compile in smoke collection pipe road 2, at first in jar, cool off by refrigerated separation jar 3, isolate liquid such as wood tar, remaining flue dust continues to be transported to by smoke collection pipe road 2 combustion chamber of sawdust drying oven 5, burns, and is used for the preheating and the oven dry of sawdust, gas after the burning mainly contains carbon dioxide and steam, is discharged by chimney.

Detect through authoritative environmental administration, the concentration of emission of flue dust is before recycling: 835.5mg/Ndm ³, discharge capacity is 2.6kg/h, does not reach discharging standards; Recycling the back concentration of emission is: 168.3mg/Ndm ³, discharge capacity is 2.6kg/h, reaches discharging standards fully, efficiency of dust collection is 80%.
